What is it?
Hyperhidrosis (excessive sweating) is the production of excess sweat, beyond the amount required to return elevated body temperature back to normal.

What areas does it affect?
Hyperhidrosis can be generalized or focal.

Generalised hyperhidrosis affects the entire body, the cause may be unknown, or it may be due to an underlying medical condition. These conditions can be identified on history, examination and investigations.

Focal hyperhidrosis affects specific sites of the body, most commonly the armpits, palms, soles or head/face. Focal hyperhidrosis typically occurs in otherwise healthy people, commonly before the age of 25.

How common is it?
It is estimated to affect about 3% of the general population.

Is it genetic?
Roughly two thirds of patients report a positive family history
